Patented Dec. 7, 1920,

Application filed July 7, 1914. Serial No. 849,579.

To all whom it may concern:

Be it known that we, VVILLIAH NICHOLAS, a subject of the King of Great Britain, residing at No. 222 West Twenty-Third street, in the city of New York, county and State of New York. and WILLIAM AGKERMAN, a citizen of the United States, residing in the village of Larchmont, in the county of estchester, in said State, have invented new and useful Improvements in Type Justifying and Composing Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

Our invention relates to type composing machines and more particularly to that class in which a record is made of the set-wise body size of the characters to be composed into justified lines, such record being thereafter employed in reproducing the type and effecting the justification thereof.

In machines of this type, in order to attain to theoretically accurate spacing or justification of the lines composed thereon, the set or width of the characters is cast in multiples of a predetermined unit value, and in the present invention we employ the system heretofore adapted by us in connection with Patents #964,677, #964,678 and #964,679, wherein the unit is taken as 1 g of an em, that is, substantially of the pointwise dimension of the type body.

Various methods have been employed for registering the accumulated unit measurement of types to be justified into lines of given length, and for making a record in accordance therewith to control the casting mechanism in producing justifying spaces of the requiredsize or sizes. For example in our said Patent No. 964,678, we illustrate form of record. to be used for this purpose, comprising a tape in which perforations are definitely located thereon to select not only the proper character butalso to determine the size of both the character types and the justification spaces; while in our said Patent No. 964,679 mechanical selector devices are used to accomplish the same purpose,

but in a somewhat different manner. That is to say, in the first mentioned method a plurality of magnets actuate a series of perforating punches and in the latter, movable collars are shifted tosymbolic positions determined by stops operated through electric magnets substantially in the same manner as the punches are actuated in preparing the tape record.

Our present inventionwill therefore be adaptable, with unimportant modifications of mlnor parts, in preparing either form of record and may accordingly be employed with mechanism for perforatmg tape to be used in connection with casting machines, or, in setting other kinds of selector devices for the same purpose. Furthermore, in machines of this class indicated, various means have been devised for connecting the individual character and space keys with corresponding mechanisms such as the punches for making the holes in the tape records, and in operating the fingers or levers by means of which the selector devices have been set to that end. In this particular also we wish to point out at the opening of the specification that while we illustrate a form of mechanism applicable to the latter method in which electric circuits are employed in setting the selectors to constitute the controller record, and while various wiring schemes to that end have been illustrated, it is not our intention to limit the application of our device to any one form of record or to any specific means for making either the one or the other of said records.

An object of our invention is, therefore, to provide more efficient and accurate ineans for registering the unit measurements of character types to be justified into lines.

Another object of this invention is to provide improved mechanism for selecting and controlling mechanism whereby a record may be made to effect the justification of the lines which have been theretofore measured and such measurements regis tered.

Another object of this invention is to provide mechanical means for setting and controlling ele tric devices whereby a record is established of the unit size of spaces required to justify lines of type. I

A further object of this invention is to provide mechanical means by 'which the unit value of spaces is recorded by the depression of a key, representing in terms of unit values the aggregate shortage of the line to be justified.

A further object of our invention is to provide mechanical means for recording justification records for lines of type.

Other objects of the invention will appear from the following detailed description of the invention, in connection with the accompanying drawings of which:

A description of the mechanism employed by us maybe conveniently yet more or less arbitrarily, included under three heads, namely, Yea) registering means, for recording the unit v n-us r characters composing lin t S t; us y n m h s fdr'fiutomatically determiningthe unit value r'jascifyingspacesrequiredin'the individual lines of such composition; and, incidentally (c) the mechanism including electric and other connections, whereby such ascertained unit values are first recorded and then used in casting both the characters and the justifying spaces to compose lines of type.

In order more clearly to understand the construction and operation of the several parts that constitute the embodiment of the mechanism illustrated herein, it is deemed advisable at this point to refer in general terms to those features of the casting machine which are controlled by the record to be prepared by our invention for casting the justified lines.

In type casting machines of the class mentioned, the matrices are arranged in a single plate in parallel rows, having the individual matrices of the several rows disposed in like parallel arrangement in lines at right angles to the rows, so that by shifting the plate in either direction to a position over a common mold in which the body of a single type is cast, the required matrix may be brought into registration therewith, to formthc" desired character, the set. of

all characters of a given row having the V series is thrown into engagingrelationship with the matrix moving mechanism, a corresponding row, and a corresponding individual matrix in that row, will be brought into position over said mold to cast the desired type, it having been further provided that the type sizing mechanism is simultaneously set to the unit value of the row matrix thus selected. In our said patents the particular means described for determining the sizes of the individual type comprises a stepped slide that moves transversely across the path of the sliding or ad justable wall of the type mold and succe. sively presents thereto abutting surfaces at varying depths corresponding to different unit values of the types, so that by arranging another series of stops in proper relationship with means for interposiing any given step of the type sizing slideinto the path of the mold slide, the latter may be arrested in a position to set the mold to any required unit size, corresponding with the selector row of matrices.

, The arrangement above referred to wherein the row stops of the matrix centering mechanism are operably connected with the type sizing slide, refers to the casting of the character type'and spaces composing ordinary'dines of composition. In order to cast justifying spaces a further mechanism called the justifier is employed as a part of the casting machine f r'gaging the mold stops to, various unit dimensions for different sizes of space, and, therefore it is the general purpose of' our present invention to provide a mechanism for setting the justifier, so called, of the casting machine, which justifier mechanism will presently be reverted to in this connection.

When electric magnets are employed to actuate the various stops, as in the form of machine to which the herein illustrated embodiment of our invention relates, for the purpose of setting the character types, the row stop magnets are connected in series with corresponding mold stop magnets which in like manner locate the stepped slide of the said type sizing mechanism, so that when any one of the matrices of a selected row is thus located the type body mold will accordingly be set to the proper unit size.

For casting the justifying spaces, however, the mold stops are adapted to be operated by a second set of electromagnets which have their terminals so arranged that the justifier mechanism oi. the caster may se leet all of the spaces of the same size, or a given number of one size and the remainder of the next higher or next lower unit value, To this end tie mold stop terminals of the justifier mechanism are arranged in two rows side by side in which the terminals of odd and even unit values are set one opposite the other, in connection with which are arranged a series of electro-magnetically operated stops in similar arrangement, which, being in parallel rows with the terminals of the mold stops, are adapted when interposed in the path thereof to locate two separately actuated sliding contact fingers through either of which the current may be conducted into the different mold sizing stops, as required, the one finger conducting the justifier current into one of the even unit mold stop terminals the other into an odd unit terminal thereof. The magnets of the stops which thus locate the contact fingers of the mold-stopanagnet terminals through one of which it has been seen the current must pass to energize the corre sponding mold stop magnet and which are called the justifier stops in our said patent, are connected by a series of twelve elect circuits each of TVl1li'll successively connects in series two of the said justifier stops. Ur to be more particularly described, the first of said currents has in series stops relating to the terminals of both the four and five unit mold stops, the second circuit likewise connects the fire and six unit stops, and in a similar manner the other justifier stops are elect "ically connected in se ries in like pairs, excepting the stop corresponding to the 15 units space, which singly is controlled by the 12th or last circuit of the series, the stop for the 16 units and a second stop for ma nets to two sizes of spaces diiierin in b .L 7 D value by one unit, either of which may be energized to produce the particular space size to which it has thus been set and accordingly that size may be used entirely in the justification of a line, or a given number of either, and the remainder of the other size, by merely shifting the current at the proper time from the one contact finger to the other.

To this end, namely, in order to thus change the circuit from the odd to the even unit mold sizing stop, a circuit changing device is employed having two separately insulated contact surfaces longitudinally disposed in the direction of the travel of a sliding contact connected with the main justifier setting circuit, which as it moves from the one to the other of said longitudinally disposed contacts of the circuit changing device is accordingly electrically connected first to the sliding contact finger'of the even units, and then after the predetermined number of even unit space selections the traveling contact passes on to engage the contact that connects to the sliding fingers of the odd unit terminals of the mold sizing mechanism.

The traveling contact has a step by step movement and is designed to move a definite distance, 2'. 6., a given number of steps, one for each space cast and inserted in the line, and therefore to determine the number of even spaces that shall be cast first the cir cuit changing device is accordingly set at the proper position longitudinally of the path of the traveling contact to effect the change after the given number of insertions of the even unit spaces. This traveling contact is therefore set to an operable position in accordance with the predetermined number of spaces of a given size required by means of the justifier lever, so called, which setting of the justifier lever, is accomplished by first carrying it to the highest possible position against a spring yielding means by the reaction of which the lever is carried into a setting position against that one of a series oi justifier lever stops corresponding to the number needed. It has been ascertained that in justifying all lines having "from 1 to 20 spaces, of 6dunits maximum shortage, where spaces of two different sizes are required to effectuate even spacing not to exceed 9 spaces of either size will be required. Accordingly 9 electric circuits are used and these have their contacts conveniently grouped in the relative position of the individual circuits of the character casting mechanism above mentioned, and which in relation to the circuit closing index mechanism presently to be referred to, will have their circuit closing device located on the individual side of the mechanism and will therefore be referred to as individual circuits exclusively.

In the normal operation of the traveling contact to change the values of justifying spaces it will therefore operate to cast only spaces of even units to a definite number, which even unit spaces will therefore be the first to be cast in the operation thereof. Hence it has been found necessary to change this order and in certain ascertained cases to insert the odd unit spaces first to a predetermined number and to supply the remainder in even unit values. This is accom plished by introducing a simple circuit changing device operated by an electromagnet which in our said patent is termed the shift magnet, requiring but a single electric circuit, called the shift circuit to distinguish it from the row circuits of the justifier stop magnets on the one hand, and the individual circuits of the justifier lever stop magnets, on the other.

Itremains to be pointed out in this connection that inasmuch as the justifier is set only once for each line and previous to the commencement of the casting thereof, that the same row and individual contact positions as used in connection with the casting of the ordinary characters and spaces, may also be similarly employed for the purpose by setting the various justifier stops above referred to. This is accomplished by introducing a slidable switch mechanism operated by means of a cam upon the actuating shaft of the casting mechanism by means of which the switch is operated to carry the contacts pertaining to the respective rows and individuals into position to set the said justifier parts and then to return them to restore the connections for the ordinary casting; and accordingly the circuits which have their terminals at the point or at the level to which this switch is elevated and which operate the various mechanisms of the justifier, are called the setting circuits, while those which have their terminals at the lower level and connect with the stops em 'ployed' in the casting of the characters and spaces of regular composition, are likewise termed the working circuits, and will be hereinafter thus referred to. The row matrix stops which in this class of type casting'machines are those connected in'series with the type sizing stops are actuated simultaneously with the individual matrix stops, consequently working circuits corresponding thereto are energized at the same space to be inserted in the line.

time and thereforethe same controller device or selector will make-both connections. In like manner different features of the justifier setting mechanism are simultaneously operated so that a single justifier controller or selector makes the contacts to set the mechanism which locates the contact sliding fingers at various type sizing positions and also makes the contacts for setting the justifier lever which-it has been seen sets the mechanism to control the slide that determines the number of a given size of In the justifier setting mechanism ofmachines of the class to which reference is nowbeing made the justifier lever is controlled by the individual positions of the selector while the mold sizing stops are simultaneously controlled by the row positions thereof.

In order to energize the working and setting circuits above referred .to according to the various combinations required in composing and justifying lines of type a plurality of circuit closing devices are grouped into what is known in the art as the index head of the casting machine, which conforms in construction and operation to the particular style of record controller employed. In whatever system adopted the selector row and individual circuits are adapted to receive current simultaneously, and have their respective contacts arr nged in such index head in numerically consecutive row and individual positions each from 1 to 15 positions, more or less, accord ing to the number of characters cast by the machine; although on the setting side of the switch to which the wires lead from the index head as has been pointed out, not all of the row and individual positions are required for setting thejustifier mechanism.

In the present embodiment of our invention, as already explained, we employ mechanism designed to prepare a controller comprising a succession of selectors with movable members thereon to actuate row and individual contact levers of the index head in order to close said row and individual circuits which as has been seen may be either the working circuits employed in casting character type and spaces, or the setting circuits of the justifier such as is dis closed in our Patent #964,67 9. A controller selector 220 as described in said patent is employed here having upon the shaft thereof collars 221, 222, and 223 either of which may be shifted longitudinally into proper position to engage any one of the corresponding row or individual circuits.

Therefore to cast a type or space of whatever size theretofore determined by action of the setting circuits two contacts are usually necessary for the working circuits and only two, namely, one to energize both row matrix and mold electromagnets in' series (for casting spaces the current passing to the mold stop magnets through the justilier or setting circuits) and one to energize an individual stop magnet, excepting where the last row or last individual in any row is called for, in which case the matrix plate is located by a normal, or as it is called, a dead stop, which is always in engaging position with relation to the matrix making parts. Accordingly the contact levers of the index head, not shown in the drawings, are duplicated, one set called the row levers grouped at one side, and adapted to be engaged by a collar 221 at the row side of the selector, the other or individual levers similarly disposed at the other side of the index head and in like manner adapted to engage a corresponding individual collar 222. In the mechanism to which our present invention relates as pointed out there are employed respectively 15 rows of matrices, 15 individuals in each row and that there are fifteen row, and fifteen individual contact levers, and accordingly there are 15 row positions on the half of the selector in which the collar at the side may be placed to operate, a lever while at the other side 15 individual positions are similarly located within range of the levers. In consequence when the collar on the left half of the selector shaft, for example, is carried to any one of the fifteen positions, say the last or fifteenth, it will engage the corresponding 15th individual contact lever; and likewise when the collar on the other half of the selector is in the first, second or other row position it will similarly engage the row lever to energize the corresponding row and mold stop magnets. Thus are the character types cast in the order required for composition: it remains briefly to outline the prerequisites for manipulating the same mechanism for easting the justifying spaces.

The space matrix in the machine of our said Patent #964,679 is located in the last or fifteenth row (and in the eighth individual in said row) and as has been seen no selector collar is required on the space controller to locate that row of the matrix plate over he mold; the position row fifteen on the controller selector for spaces is therefore available to close a circuit for other purposes and is accordingly employed to make connections for the iustiiier circuit, so called, which, as pointed out by virtue of the di'lferent settings of the justitier parts is used in casting the various sizes of justifying spaces.

Therefore when a space selector follows the selector representing characters composing a word, an individual collar thereon displaces an individual contact lever to cause the'matrix plate to locate the 8th individual over the type mold, and the fifteenth row of the matrix plate will be presented which will then be in position for casting a space of any size. The row collar of the space selector being in said fifteenth row position will cause the corresponding row contact levers to turn the current through the justilier circuits whereupon it will set the mold to produce the predetermined size of justify space.

Inasmuch, therefore as the positions of the selectors control the operations of the casting machine, it is the function of our present invention to provide improved means for properly locating the selector collars or tape perforations which not only control the selection of the particular characters required, but also determine the space to be selected.

Two keyboards 1 and 16 are employed in the preparation of the controller by our machine, the one comprising the character keys 5 grouped in 15 rows of 15 each also the space key 10 and certain keys for special purposes which will hereafter be explained, the other keyboard 16 relating to the justifier mechanism proper, having 64 keys 15 one for each possible justification of from 1 to 64 units. The character keys are preferably arranged according to the so-called universal standard keyboard, irrespective of the row or individual arrangement in the matrix plate of the casting and composing mechanisms, a multiple switch mechanism 2, similar to that described in our former patents (see Figs. 3 and 4) being employed whereby'it is permitted that the wires of a circuit of any given row or individual stop magnet may be terminated at any convenient posit-ion on the keyboard.

Each of the character keys 5, see Fig. 2, with certain exceptions to be noted, has two contact pins, one terminating in a contact point adapted upon its depression to close a circuit having in series the unit row mold stop magnets, the other contact similarly connecting with an individual stop magnet, a row king, and likewise an individual king magnet being connected in series with each of the corresponding row and individual stop magnets, for setting in operable position the respective row and inclividual collars of the controller selectors in the same manner as provided in our former patent referred to above, and which will hereafter be referred to in greater detail. The space key 10 likewise has two rying at their respective lower ends the circuit closing contacts, respectively, one contact making the circuit which includes the eighth individual stop magnet, the other contact connecting in series the space escapement and l-unit stop magnets, we having constituted the four-unit the minimum size of space to be cast.

As already pointed out, the 15th row and stems car the 15th; individual being in the last lineon their respective sides of the matrix plate ofv matrix blank being located in the '15throw,

the contact of the space key is not employed for settingva row stop magnet. It is nevertheless necessary to operate the king row magnetby. the space key in orderto place m tual: for the space selectorin the 15th rowposition, for the uses of the casting na-v chine in ca sting justifying spaces as explained,. which by the closing of the said space bar contact is accordingly done at the same time thatit causes to be energizedthe spaceescapement magnet 130, Fig. 14, of the j ustifier device, which it will, be seen in connection withthe descriptionof that mecha-, nism must operateeach time a. space is inserted between thev words of the line.

Thespace key and character keys are in' dependently. connected with a rod 8 on the depression of each of the said keys, adapted to move longitudinally towardthe contact v9 at the backof the keyboard, which in turn is connected witha relay circuit by means of which thevarious magnet circuits are in turnseverally orljointly energized, in a manner presently to be described more in detail. e introduce a current. through the keyboard into the individual keys in'our. present v invention in the same manner as that hereto-.

At the side of the dial 21 for counting ems is a supplemental-rotating dial 22, which has upon the rim thereof successive markings representing a plurality of similargraduations of sixteenunits each. Only enough of the dial22 is visible through-the concentric slot-.24 -to show at its upperside, 16 of said unit graduations the equivalent of one emonthe other dial 21. The shortsha-ft 26 upon the end of which is the .pointer 25 (see Figs. 1 and 6) is connected bychain gears to the shaft123" which extends. entirely; through the unit register mechanism, upon the end of'which is fixed the rotating dial 22,. so that a positive connection is established betweenthe saidunit dial 22 and the pointed finger25 by means of which is made possible the finerreading of the units that compose the ems of .the larger dial.

The main shaft. 23 of the unit measuringmechanism which is supported upon the upright brackets 23 and.23 is actuated in the present embodiment of our invention by. means of a spring motor3Q comprising the ordinary typejof clock spring 31, which is contained within the drum 30, one end of they spring being secured to the shaft 23, the other to said drum (see Fig. 11). The drum is pinned to the sleeve 32 which is loosely mounted upon the said shaft '23and similarly secured thereonthe ratchet wheel 33'.

forward motion is imparted to the ratchet by means of a pawl 3twhich. is pivotally attached to a lever arm .35. and is held upon the periphery of the ratchet wheel bythe pressure of a coil spring 34 Upon the hub of the lever 35 is an arm 37 which by means of .link connection to the driving mechanism as will be explained, isgiven a' rocking motion wherebv'the ratchet pawl 34 willcarry the wheel 33 forward and with it the drum 30, which is the usual manner, ofwmding similar springs and tends to wind or charge the spring motor 30 with I each forward impulse of said pawl. Ada tent '37. attached to the post38. retainsthe ratchet ried' by the pawl .34 byaction of the spring 33 in theposition to which. it is car The actuating lever arm 37 is connected directly by yielding means to the driving mechanism of the casting machine when our registering mechanism is operated in connection with such a machine, which will operate to propel the spring winding ratchet 33, until the spring 31 has been raised to an equal tension to an actuating spring of the driving mechanism, thereby enabling the drum 30 to be set by mechanical means. The spring 31 being attached at one end to the shaft 23, when wound to the desired tension supplies the power to rotate the shaft in a given direction until counteracted by other means.

The shaft 23 it will be recalled, is operably connected with the shaft 26 of the pointer 25, and has upon its end the dial 22, to disclose to the operator the number of units set by him, and it will therefore be necessary in order to register the units to limit the rotation of the shaft 23 against the action of the spring 31, in accordance with the unit requirements of the various characters, so that it will always accurately record the units set. Therefore I have provided a stop lever 40 (see Fig. 10) adjacent a gear wheel ll pinned to said shaft, which extends beyond the periphery of the gear wheel 41, so that as it swings upon the shaft 23 it is adapted to engage any one of the series of stop pins 45 arranged in two parallel rows in a block 46. These pins are adapted to slide longitudinally within suitable bearings in said block, being normally held by means of springs 47, in the position shown in Fig. 8 having their forward ends flush with the surface thereof adjacent the swinging arm e0. A bank of electro-magnets 50 are provided with armature levers 51 pivotally supported midway of their length and adapted when said magnets are successively energized to cause the free end of the respective levers to impinge against corresponding pins 45 forcing them against the action of their springs 47 to project beyond the face of the block 46 into the path of the swinging lever arm 40. The stop lever arm 40 is normally held against an adjustable stop 42 by means of a spring 43, one end of which contacts a pin projecting from an upward extension of the lever 4:0, the other end of the spring being secured to the middle bracket supporting the shaft 23.

The stop magnets 50 are connected in series with corresponding row stop magnets 207 of the selector setting mechanism hereinafter explained, (see Figs. 29 and 30) after passing through a peculiar layout switch between the respective row and unit stop magnets, whereby the row magnet connections are converted into the proper unit value; it is apparent that the rows as they have been established with reference primarily to the selector locations of the ma triX plate, in many given instances will not conform to the successive order in which the unit stops are arranged. The details of the construction of this switch and also that whereby the characters layout is converted into the order of arrangement re quired for the various row and individual circuit connections, have been fully described in our said patents and therefore will not be referred to in this except to point out that both of the layout switch blocks are here employed in the same manner and of the same construction as described in said patents. The general scheme of keyboard wiring is therefore also similar to that described in said patents as will be seen by referring to Figs. 2, 3, 4 and 5. The switchiblock 2230 (Figs. 2 and 3) on the keyboard, comprises the insulated parallel plates 281 connected by pins 232 passing through enlarged openings 233 in the plates to which the pins are not electrically connected to conduct the respective current from the keyboard to the proper stop magnets above described.

The operable tension spring which holds the stop lever normally against the fixed stop 42 is of only suflicient strength to main tain that member in such normal position of rest and means are provided next to be described whereby this lever may be operably attached to the gear wheel 41 and by action of that member carried against the appropriate stop pin selected in the course of composition. To this end, therefore, the stop actuating gear wheel 11 has provided a locking means which consists of a longitudinally moving slide 55 with teeth 55 at its end which lock-slide is held against lateral movement by guide bearings 56 within a bracket immediately above the periphery thereof and is adapted to mesh with the teeth of said gear upon being forced in the direction thereof. (See Fig. 10. The slide 55 is moved within its bearings by means of a finger 57 which is pivotally supported upon the extension of the bracket 56 and by means of a spring 58 is normally forced downwardly by having a narrow end 57 enter a transverse guide slot 59 in the lock slide 55, so that normally by action of the spring 58 the gear lock 55 is held within its lateral guide walls in mesh with the said stop actuating gear 11 thereby securely holding the latter in the position to which it may be advanced. Means are provided for lifting the finger 57 and thereby unlocking the gear wheel 41 when it is required to rotate the same, comprising an electro-magnet which may be termed the counter con-
